DMO Group Call
General
In DMO, the MTH800 can be used without your Service
Provider’s infrastructure.
Direct Mode allows communication with other terminals also
operating in Direct Mode, which are on the same frequency
and talkgroup as your MTH800.
You can receive a call:
• From the selected talkgroup
• From other users within talkback range (if configured by
your Service Provider). This is called an InterMNI (Mobile
Network identity) call.
• From an open group. (An open group is a super-group to
which all DMO groups belong.)
When you start a call, the members of the selected talkgroup
who have their units turned on, and are within the group
subscriber identity (as configured by the Service Provider),
will receive the transmission.
In DMO the MTH800 can communicate with the trunking
system (and vice-versa) if the Gateway option is enabled in
the MTH800.
Dual Microphone Feature
See “How to Hold Your MTH800” on page 13.
“My Groups” Folder
You can organise your favourite groups into one folder called
“My Groups”.
In DMO it is only possible to place Group Calls and Emergency Group
Calls.
